The short answer
Most Orlando homes need a full exterior wash once a year. High-traffic concrete and shaded, damp areas may need attention twice a year. Roofs can usually go two to three years between soft washes. That is the Florida schedule — and Florida is harder on exteriors than almost anywhere else in the country.
Why Florida is different
Humidity. Orlando sits in near-constant humidity for much of the year. Moisture feeds algae, mildew, and mold, which is why the north side of a Florida home can turn green in months, not years.
Heat plus rain. Hot afternoons and daily summer downpours are a perfect recipe for growth on siding, fences, and concrete. Surfaces rarely stay dry long enough to discourage it.
Oak pollen season. Every spring, live oaks dump a thick yellow-green coat of pollen over everything — cars, roofs, driveways, pool decks. Washing before pollen season ends is wasted effort; washing after it clears is one of the most satisfying home projects there is.
Hurricane season. June through November brings tropical systems that plaster homes with debris, dirt, and standing-water staining. Many homeowners schedule a wash after storm season closes.
Shade and trees. Big oaks and palms are wonderful until their shade keeps your siding damp all day. Shaded walls, fences under tree lines, and patios that never see sun grow algae fastest and need the most frequent attention.
A surface-by-surface schedule
House siding: once a year. Stucco, vinyl, and fiber cement all collect algae and mildew over a Florida year. An annual house soft wash keeps growth from taking hold and keeps the paint underneath lasting longer.
Driveway and walkways: once a year, sometimes twice. Concrete shows tire marks, oil drips, and algae quickly, especially shaded sections. Driveways under oak trees may want a second pass in the fall. See our driveway cleaning page.
Roof: every two to three years. The black streaks on Florida roofs are algae that feeds on the limestone in shingles. A roof soft wash kills it at the root. Do not let anyone talk you into annual high-pressure roof cleaning — it is unnecessary and damaging.
Pool deck and screen enclosure: once a year. Pool decks get sunscreen, body oils, and constant moisture — a slippery, stained combination. Annual cleaning keeps the deck safe to walk on and looking sharp.
Fence: every one to two years. Wood and vinyl fences along shaded property lines green up fast. Regular washing extends the life of the material.
Gutters: once a year. The outside of gutters collects the same algae streaks as siding. Brightening them during the annual house wash is efficient.
Signs it is time, whatever the calendar says
Green or black tint on siding, especially the north side. Dark streaks running down from gutters. A driveway that looks gray even when dry. Slippery-feeling concrete around the pool. Black streaks on the roof visible from the street. A fence that used to be white. Any of these means the schedule has slipped — book the wash rather than waiting for the next round date.
The cost of waiting too long
Algae and mildew are not just ugly. Left alone, algae roots into porous surfaces and holds moisture against them. On roofs, that shortens shingle life. On wood, it speeds rot. On concrete, it makes surfaces dangerously slick. A yearly wash is cheap maintenance; replacing a roof or a deck early is not.
Build your yearly rhythm
A simple Florida rhythm works for most homes: late spring (after oak pollen season) for the house wash and pool deck, late fall (after hurricane season) for the driveway and a second look at shaded areas, and a roof soft wash every two to three years whenever the streaks return. Put it on the calendar like an oil change and you will never be the green house on the block.

Frequently asked questions
Is once a year really enough in Florida?
For most homes, yes — an annual house wash plus annual concrete cleaning keeps algae and mildew under control. Homes with heavy shade, lots of trees, or north-facing walls that never see sun may need trouble spots touched up twice a year.
Should I wash before or after oak pollen season?
After. Oak pollen coats everything in a sticky yellow film each spring, and washing before it finishes means washing twice. Wait until the pollen drops off, then wash — the results last much longer.
How often should a Florida roof be washed?
Every two to three years with a soft wash is the right cadence for most roofs. The black streaks are algae, and a proper soft wash kills it at the root so it stays gone longer. Annual pressure washing of a roof is overkill and risks damage.
Does hurricane season change the schedule?
It can. Storms leave debris, dirt wash-down, and standing-water stains on driveways and lower siding. Many homeowners plan their fall wash for after hurricane season ends so one cleaning handles the whole mess.
What happens if I skip washing for a few years?
Growth gets a deeper foothold, stains set harder, and some surfaces take real damage — algae shortens roof life and rots wood faster. A neglected home also costs more to clean when you finally do it, because the job is bigger. Regular washing is cheaper than catch-up washing.
